Kinetic energy is defined simply as the energy required to do work. An object in motion will have kinetic energy, although some potential energy may be in existence at certain times in its motion. There are several types of kinetic energy, but the important one for this lesson is transitional kinetic energy. Kinetic energy is defined as being ˝ mass × volume˛.
There are other types of kinetic energy, but they're not important for this lesson.
